RUNUSER(1) User Commands RUNUSER(1)
NAME
runuser - run a shell with substitute user and group IDs
SYNOPSIS
runuser [OPTION]... [-] [USER [ARG]...]
DESCRIPTION
Change the effective user id and group id to that of USER. Only ses‐
sion PAM hooks are run, and there is no password prompt. This command
is useful only when run as the root user. If run as a non-root user
without privilege to set user ID, the command will fail as the binary
is not setuid. As runuser doesn't run auth and account PAM hooks, it
runs with lower overhead than su.
-, -l, --login
make the shell a login shell, uses runuser-l PAM file instead of
default one, clears all envvars except for TERM, initializes
HOME, SHELL, USER, LOGNAME and PATH
-g --group=group
specify the primary group
-G --supp-group=group
specify a supplemental group
-c, --command=COMMAND
pass a single COMMAND to the shell with -c
--session-command=COMMAND
pass a single COMMAND to the shell with -c and do not create a
new session
-f, --fast
pass -f to the shell (for csh or tcsh)
-m, --preserve-environment
do not reset HOME, SHELL, USER, LOGNAME environment variables
-p same as -m
-s, --shell=SHELL
run SHELL if /etc/shells allows it
--help display this help and exit
--version
output version information and exit
A mere - implies -l. If USER not given, assume root.
